caldist: Calculate calibrated distribution

In IntCal: Radiocarbon Calibration Curves

Calculate calibrated distribution

Description

Calculate the calibrated distribution of a radiocarbon date.

Usage

caldist(
  age,
  error,
  cc = 1,
  postbomb = FALSE,
  yrsteps = FALSE,
  threshold = 0.001,
  calibt = FALSE,
  BCAD = FALSE,
  rule = 1,
  ccdir = NULL
)

Arguments

age	Uncalibrated radiocarbon age
error	Lab error of the radiocarbon age
cc	Calibration curve to use. Defaults to IntCal20 (cc=1).
postbomb	Whether or not to use a postbomb curve. Required for negative radiocarbon ages.
yrsteps	Steps to use for interpolation. Defaults to the cal BP steps in the calibration curve
threshold	Report only values above a threshold. Defaults to threshold=1e-6.
calibt	Use the student-t distribution as alternative to the normal distribution. Requires 2 parameters, e.g., calibt=c(3,4), defaults to FALSE.
BCAD	Which calendar scale to use. Defaults to cal BP, BCAD=FALSE.
rule	Which extrapolation rule to use. Defaults to rule=1 which returns NAs.
ccdir	Directory of the calibration curves. Defaults to where the package's files are stored (system.file), but can be set to, e.g., ccdir="curves".

Examples

calib <- caldist(130,20)
plot(calib, type="l")
postbomb <- caldist(-3030, 20, "nh1", BCAD=TRUE)
